The correct statement among the following is

Options

  1. AElectromagnetic waves cannot travel in vacuum
  2. BElectromagnetic waves are longitudinal waves
  3. CElectromagnetic waves are produced by charges moving with uniform velocity
  4. DElectromagnetic waves carry both energy and momentum as they propagate through space.

Correct answer

D. Electromagnetic waves carry both energy and momentum as they propagate through space.

Step-by-step solution

(a) is incorrect because EM wave doesn't require any medium to travel thus they can travel in vacuum. (b) is incorrect because EM waves are transverse waves. (c) is incorrect because EM waves are produced by an accelerating charge. (d) is correct as EM waves carry both energy and momentum.
